CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

We unified the Freescale pci/pcie initialization by changing the fsl_pci
to a platform driver. In previous PCI code architecture the initialization
routine is called at board_setup_arch stage. Now the initialization is done
in probe function which is architectural better. Also It's convenient for
adding PM support for PCI controller in later patch.
Now we registered pci controllers as platform devices. So we combine two
initialization code as one platform driver.

In order to avoid loosing error events, it is desirable to group
error events together and generate a single trace for several identical
errors.
The trace API already allows reporting multiple errors. Change the
handle_error function to also allow that.
The changes at the drivers were made by this small script:
$file .=$_ while (<>);
$file =~ s/(edac_mc_handle_error)\s*\(([^\,]+)\,([^\,]+)\,/$1($2,$3, 1,/g;
print $file;

Remove the arch-dependent parameter, as it were not used,
as the MCE tracepoint weren't implemented. It probably doesn't
make sense to have an MCE-specific tracepoint, as this will
cost more bytes at the tracepoint, and tracepoint is not free.
The changes at the EDAC drivers were done by this small perl script:
$file .=$_ while (<>);
$file =~ s/(edac_mc_handle_error)\s*\(([^\;]+)\,([^\,\)]+)\s*\)/$1($2)/g;
print $file;

The debug macro already adds that. Most of the work here was
made by this small script:
$f .=$_ while (<>);
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*": /\1"/g;
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*/\1/g;
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*"MC: /\1"/g;
$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;
$f =~ s/\"MC\: \\n\"/"MC:\\n"/g;
print $f;
After running the script, manual cleanups were done to fix it the remaining
places.
While here, removed the __LINE__ on most places, as it doesn't actually give
useful info on most places.

Kernel kobjects have rigid rules: each container object should be
dynamically allocated, and can't be allocated into a single kmalloc.
EDAC never obeyed this rule: it has a single malloc function that
allocates all needed data into a single kzalloc.
As this is not accepted anymore, change the allocation schema of the
EDAC *_info structs to enforce this Kernel standard.

Now that the EDAC core supports struct device, there's no sense on
having any logic at the EDAC core to simulate it. So, instead of adding
such logic there, change the logic at mpc85xx_edac to use it
compile-tested only.

As EDAC doesn't use struct device itself, it created a parent dev
pointer called as "pdev". Now that we'll be converting it to use
struct device, instead of struct devsys, this needs to be fixed.

The number of pages is a dimm property. Move it to the dimm struct.
After this change, it is possible to add sysfs nodes for the DIMM's that
will properly represent the DIMM stick properties, including its size.
A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when
the memory controller represents the memory via chip select rows.

On systems based on chip select rows, all channels need to use memories
with the same properties, otherwise the memories on channels A and B
won't be recognized.
However, such assumption is not true for all types of memory
controllers.
Controllers for FB-DIMM's don't have such requirements.
Also, modern Intel controllers seem to be capable of handling such
differences.
So, we need to get rid of storing the DIMM information into a per-csrow
data, storing it, instead at the right place.
The first step is to move grain, mtype, dtype and edac_mode to the
per-dimm struct.

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver. This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.
This patch is a pretty mechanical change. The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial. This patch looks big and scary because it touches so
many files, but it should be pretty safe.

implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

Add the ability to detect the specific data line or ECC line which failed
when printing out SDRAM single-bit errors. An example of a single-bit
SDRAM ECC error is below:
EDAC MPC85xx MC1: Err Detect Register: 0x80000004
EDAC MPC85xx MC1: Faulty data bit: 59
EDAC MPC85xx MC1: Expected Data / ECC: 0x7f80d000_409effa0 / 0x6d
EDAC MPC85xx MC1: Captured Data / ECC: 0x7780d000_409effa0 / 0x6d
EDAC MPC85xx MC1: Err addr: 0x00031ca0
EDAC MPC85xx MC1: PFN: 0x00000031
Knowning which specific data or ECC line caused an error can be useful in
tracking down hardware issues such as improperly terminated signals, loose
pins, etc.
Note that this feature is only currently enabled for 64-bit wide data
buses, 32-bit wide bus support should be added.
I don't have any 32-bit wide systems to test on. If someone has one and
is willing to give this patch a shot with the check for a 64-bit data bus
removed it would be much appreciated and I can re-submit with both 32 and
64 bit buses supported.

With a 64-bit wide data bus only the lowest 8-bits of the ECC syndrome are
relevant. With a 32-bit wide data bus only the lowest 16-bits are
relevant on most architectures.
Without this change, the ECC syndrome displayed can be mildly confusing,
eg:
EDAC MPC85xx MC1: syndrome: 0x25252525
When in reality the ECC syndrome is 0x25.
A variety of Freescale manuals say a variety of different things about how
to decode the CAPTURE_ECC (syndrome) register. I don't have a system with
a 32-bit bus to test on, but I believe the change is correct. It'd be
good to get an ACK from someone at Freescale about this change though.

Some unused, unsupported debug code existed in the mpc85xx EDAC driver

Commit b4846251727a38a7f248e41308c060995371dd05 ("edac: mpc85xx add
mpc83xx support") accidentally broke how a chip select's first and last
page addresses are calculated. The page addresses are being shifted too
far right by PAGE_SHIFT. This results in errors such as:
EDAC MPC85xx MC1: Err addr: 0x003075c0
EDAC MPC85xx MC1: PFN: 0x00000307
EDAC MPC85xx MC1: PFN out of range!
EDAC MC1: INTERNAL ERROR: row out of range (4 >= 4)
EDAC MC1: CE - no information available: INTERNAL ERROR
The vaule of PAGE_SHIFT is already being taken into consideration during
the calculation of the 'start' and 'end' variables, thus it is not
necessary to account for it again when setting a chip select's first and
last page address.

Add support for the Freescale MPC83xx memory controller to the existing
driver for the Freescale MPC85xx memory controller. The only difference
between the two processors are in the CS_BNDS register parsing code, which
has been changed so it will work on both processors.
The L2 cache controller does not exist on the MPC83xx, but the OF
subsystem will not use the driver if the device is not present in the OF
device tree.
I had to change the nr_pages calculation to make the math work out. I
checked it on my board and did the math by hand for a 64GB 85xx using 64K
pages. In both cases, nr_pages * PAGE_SIZE comes out to the correct
value.

Based on Kumar's new compatible types patch, add P2020 into MPC85xx EDAC
compatible lists so that EDAC can recognize P2020 meomry controller and L2
cache controller and export the relevant fields to sysfs.
EDAC MPC85xx DDR3 support is needed if DDR3 memory stick is installed on a
P2020DS board so that EDAC core can recognize DDR3 memory type.

All other compatibles that are uniquely identifying the processor use a
prefix of the form fsl,mpc85...'. We add support for it so we can
deprecate the older 'fsl,85...' that was improperly used here.
Additionally added mpc8536 & mpc8560 to the compatible lists.
This patch is based on Nate's 8572 patch.

This adds support for the dual-core MPC8572 processor. We have
to support making SPR changes on each core. Also, since we can
have multiple memory controllers sharing an interrupt, flag the
interrupts with IRQF_SHARED.
